Making decisions on foliar fertilizer applications
With the higher crop yields in recent years, a renewed interest in micronutrient-containing products has emerged. While most Midwest soils contain large quantities of mineral-rich rocks and organic matter containing the micronutrients needed for crops planted here, interest persists for foliar products containing micronutrients.
Whether the need for micronutrients is visually observed or measured by the best practice of paired tissue-soil samples, understanding total crop needs compared to the amount of nutrients delivered by a product can help determine which product to use.
